Hi, is there a way to slow down the DMA speed for DAC? I am using stm32F72x, and I am trying to generate a customize PWM wave from using DMA+DAC.

Hi, I fove the following code:void EXTI9_5_IRQHandler(void) { ... if(GPSDMAStart == 1){ if(currentPing == 0 && currentPingProcessed == 1){ /* currently pong, switch to ping */ hdma_uart7_rx.Instance->CR &= ~(1 << 0); hdma_uart7_...

Hi, just want to know if it is possible to switch the interrupt between Character match and Each character received interrupt on the fly without stopping the UART ?

Hi, I have the below code where I trigger the UART DMA and write to a buffer, and in the while loop I simply do a read from the buffer 1st element:MX_UART7_Init(); Uartret = HAL_UART_Receive_DMA(&huart7, uartbuf, 300); while(1){ if(Uartr...

Is there a way to stop STM32 PWM after 10 pluses ?I know one solution is using the system time and issue a stop via the code, however my issue is the stm CPU might be very busy to handle the stop signal.
